1. Field of the Invention
The present invention generally relates to an electrical connector, and more particularly to an electrical connector with a grounding plate secured therein.
2. Description of Related Art
TW patent No. M367498 discloses an electrical connector comprising an insulator, a plurality of ESATA terminals, a plurality of USB terminals and a grounding plate. The insulator defines a receptacle space running through the front face thereof and a mating tongue extending into the receptacle space along a first orientation. The mating tongue defines a first face and a second face opposite to the first surface. Each of the ESATA terminals has a contact section disposed in the first face of the mating tongue, and each of the USB terminals has a contact section disposed in the second face of the mating tongue. The grounding plate is disposed between the first and second faces of the mating tongue, and is spaced with the ESATA and USB terminals by the mating tongue. The disposition of the grounding plate efficiently prevents the electromagnetic interference of the ESATA and USB terminals. However, with the continuously development of the high frequency transmission, the signal interference between terminals is becoming obvious.
In view of the foregoing, an electrical connector with a grounding plate coupled therein is able to resolve the problem described aforementioned would be desirable.
Accordingly, an object of the present invention is to provide an electrical connector, the electrical connector has a grounding plate secured therein and used for providing good anti-electromagnetic interference ability.
In order to achieve the object set forth, an electrical connector comprises an insulative housing, a plurality of conductive terminals secured in the insulative housing and a grounding plate. The insulative housing extends along a longitudinal direction and has a base portion and a mating cavity extending forwardly from the base portion. The insulative housing defines a plurality of first passageways and second passageways separately formed in two opposite side walls communicating with the mating cavity. The conductive terminals have a plurality of first terminals and second terminals received in the corresponding first and second passageways. Each of the first and second terminals has a contact portion extending into the mating cavity. The grounding plate is disposed between the first and second terminals and defines at least one pressing portion located in the mating cavity.
In order to achieve the object set forth, an electrical connector assembly comprising a first electrical connector and a second electrical connector mated with each other. The first electrical connector includes an insulative housing, a plurality of conductive terminals secured in the insulative housing and a grounding plate. The insulative housing defines a lengthwise mating cavity, and the mating cavity runs through a front surface of the insulative housing and a inner surface of the mating cavity opposite to the front surface. The conductive terminals is disposed along a longitudinal direction, each of conductive terminals has a contact portion extending into the mating cavity and a soldering portion extending out of the insulative housing. The second electrical connector has a conductive mating portion inserted into the mating cavity. The grounding plate is secured in the insulative housing and defines at least one pressing portion disposed on the inner surface of the mating cavity.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Reference will now be made in detail to the preferred embodiment of the present invention.

What's more, the grounding plate 3 has two curve portions 34 between the body portion 32 and the head portion 33, and the two curve portions 34 separately connects the two side ends of the body portion 32 and the head portion 33 along the longitudinal direction. The curve portions 34 are higher than the body portion 32. The body portion 32, the head portion 33 and two curve portions 34 of the grounding plate 3 surround to form a lengthwise hollow portion 35 embedded in the base portion 14 of the insulative housing 1. The head portion 33 is disposed in the mating cavity 11. The disposition of the hollow portion 35 is provided for the given away of the mould so as to stamp the pressing portion 31.
In conclusion, the disposition of the grounding plate 3 and the cooperation between the grounding plate 3 and the metal shell 201 of the second electrical connector 200 are benefit to prevent the signal interference between the first and second terminals 21, 22. A good grounding circuit path will be formed when the two electrical connector 100, 200 are mated with each other, thereby the effect of the anti-electromagnetic interference is obviously improved.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrated only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
